Mechanical Design of a Orion SAJ Proof Load Fixture

Our comprehensive list of services available at EMF, Inc. includes full mechanical design and engineering support. This test fixture is used to perform proof of load testing of customer flight articles as part of the Orion Space Program. The system is designed to accommodate multiple test loads and is controlled with a pendant controller for translation. The test fixture was designed using CAD 3D modeling software. A finite element analysis (FEA) was performed to verify performance of the assembly under loading. Using this software we are able to note any stress concentrations and degree of displacement prior to fabrication.

After the accuracy of the design was verified, the machined components were manufactured in our 5-axis CNC machining centers. The steel and aluminum substrates were treated with a chemical conversion coating in the case of steel, or anodized in the case of aluminum, before being painted with a three-coat system. The finished system measures 22' in length, 22' in width, 9' in height, and weighs 20,000 lbs. This project demonstrates our ability to design, engineer, and fabricate complex mechanical systems for the aerospace industry.
